All Corner Station SEI, SUS, and ISC Guardians Are Now Paused.
J. Kissel, A. Pele Given the confusion of installation status vs what guardians are running what and why, I've brought all corner station guardians down to their equivalent SAFE or OFFLINE or UNLOCKED or DOWN state, and then paused them. These should not be unpaused again until we close up a given chamber and the install is complete. ETMX and EMTY should still be maintained under guardian control, and operators should make sure that they are fully isolated / aligned at all times until further notice.

I'm not exactly sure what happened to instigate all of this, but "guardctrl stop" should be safer than PAUSE. PAUSE is not preserved across reboots of the guardian machine. "guardctrl stop" on the other hand should actually prevent the node from being started after a reboot, which may be what you want in this case (assuming that's what happened).
